JEFFERSON B. HAYDEN, OF ABILENE, TEXAS.

DRAFT-EQUALIZER.

SPECIFICATION forming an of Letters Patent No. 748,7 dated January 1904;

Application filed April 21, 1903.

To a/IZ whom it may concern:

Be it known that I, J nnnnnson B. HAYDEN, a citizen of the United States, residing at Abilene, in the county of Taylor and State of Texas, have invented certain new and useful Improvements in Draft-Equalizers, of which the following is a specification.

My invention relates to devices for equalizing the draft where several animalsare employed, the invention relating especially to equalizers to be attached to plow-beams, and has for its object to provide means by which side draft is avoided, said means consisting of a sheave or drum on the plow-beam around which is carried a chain or cable connecting one end of a spreader-bar pivoted at the front of the beam with the animal or animals opposite the other end of the spreader-bar, the last-mentioned end of'the spreader-bar having a sheave or drum journaled thereinover which the chain or cable works.

The advantages of myinvention will appear hereinafter and by reference to the accompanying drawings, in which Figure l is a top plan View of a portion of a plow beam and axle, showing my improved draft-equalizing apparatus applied thereto; Fig. 2, a detail view of the pulley attached to the plow-beam; Fig. 3, a detail view of one end of the equalizing-lever, and Fig. 4 a crosssection of the equalizing-lever.

Referring to the drawings, in which similar reference characters indicate corresponding parts throughout the several views, A represents the plow-beam of a'sulky-plow, and B the axle.

0 represents the equalizing-lever, which is made, preferably, of sheet metal bent to form a U shape in cross-sectiomas shown in Fig. 4, which is pivoted to the end of the beam A by means of plate D, secured to the lever Q by means of pin or bolt E, passing through one of the holes Fin said lever and a hole in receive the whiffletree, to which two or more Serial No. 153.600. (No model.)

animals are hitched, while the rear end may be used to receive one end of draft-chain L, if desired, though it is generally attached to the beam by means of a U-shaped clip M, secured to the beam by means of pin or bolt N, passing through one of the holes 0 in the beam and holes in the ends of said clip. The

chain L passes around sheave or pulley P,

journaled in a boxing Q, secured on the axle B, then around sheave or pulley B, journaled in boxing S, secured to beam A, and then around pulley T, journaled in the end of lever 0, said end of the lever being split and bent around said pulley, so as to form a boxing U, as shown. The end of chain L is provided with a book, link, or other suitable attaching device to secure a whiflietree thereto.

The operation of my invention will readily appear from the above description and by re ference to the drawings.

It will be understood that the number of animals to be attached to the plow may be varied at will by changing the position of the bolt E, transferring it to the various holes F, and by varying the position of clip M by socuring it to the beam at the difierent holes 0.

Having thus described my invention, what I claim is- 1. In a draft-equalizer, a beam, a sheave journaled on said beam, an equalizing-lever made of sheet metal bent to a U shape in cross-section pivoted on said beam, a drafthook pivoted at one end of said lever, a pulley journaled at the other end, and a draftchain transposably secured to the hook end of the lever and passing loosely around the sheave on the beam and then around the pulley in the end of the lever, substantially as shown and described.

2. In a draft-equalizer, a beam, 2. sheave journaled on said beam, an equalizing-lever made of sheet metal and bent to a U shape in cross-section, a plate transposably secured to said lever and pivoted on said beam, a hook pivoted at one end of said lever, a pulley journaled in the other end, and a'draft-chain transposably secured to the hook' end of the lever and passing loosely around the sheave on the beam and then around the pulley in the end of the lever, substantially as shown and described.

3. In a draft-equalizer, a beam, a sheave lever and passing loosely around the sheave on the beam and then around the pulley in the end of the lever, substantially as shown and described.

In testimony whereof I hereto affix my signature in the presence of two witnesses.

JEFFERSON B. HAYDEN.
